10 years later...
Somewhere outside the village two boys were fighting, both 9 years old, one of them was named Yutaro Uzumaki and the other was Miroka Kakei
"Is that all you can afford?" Yutaro mocked, landing his foot on Miroka's back
"In your dreams"
Suddenly, Miroka's body turned into a log
"Kawarimi?"
After a while, Yutaro turned around and noticed several shuriken flying towards him, the son of Boruto and Sarada immediately dodged by jumping up, Miroka anticipated this and threw threads that tied the brunette's leg, then the purple-haired boy threw Yutaro to the ground
"Looks like I won"
"It's not fair, you were using Jutsu" Yutaro pouted
"It's not my fault you haven't learned any"
Suddenly, a Jounin appeared on the spot, Sarada's younger brother, his name was Hiyato Uchiha
"What are you doing here, you should be at the academy?"
"And the academy is boring, we decided to spar with each other" replied Yutaro
"Just let your mothers know about this"
Yutaro and Miroka were terrified, they immediately started begging Hiyato not to tell their mothers anything
"Please, Uncle Hiyato, don't say anything to our mothers, they will kill us" Yutaro begged
"You should have thought about it earlier"
Hiyato teleported the boys to the Hokage's office, Sarada Uchiha-Uzumaki was the eighth Hokage
A few moments later...
"Did you run away from the academy again?" Sarada said, pulling her son by the ear
"ITAAAAAA! I'm sorry, I promise I won't do it again"
"Whenever you promise me that, I stopped counting after the twenty-seventh? You won't be spared punishment, young man"
Elsewhere, Kawaki was still training
"I have reached the next level of Karma, but I am still far from Boruto's level... Why is there such a huge gap between our powers?"
Meanwhile, Boruto jumped out of some portal "No sign of any other Otsutsuki, it worries me... I wonder what to hear in the village, it's been years since I was last in Konoha, I guess I should go back"
Late in the evening, Sarada finished her work in the Hokage's office and decided to go home, in the meantime she met Himawari
"Hey Sarada, have you heard anything from older brother?"
"No, the last time we contacted him was when he passed away... It's been ten years..."
"I wonder how Boruto-nii will react to the news that he is a father"
"I'm afraid of this situation, but I'm sure he'll be a little surprised"
When Boruto and Sarada became married, Boruto went on a journey to learn about the Otsutsuki clan, and to make sure that the shinobi world was not in danger, the blonde does not even know that Sarada gave birth to his son while he was outside the village.
